To all w/wm t may concern.'

Be it known that I, SAMUEL B. MCCOR- MIGK, a citizen of the United States, residing at Otterbein, in the county of Benton and State of Indiana, have invented certain new and 'useful Improvements in Cultivators; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention relates to cultivatcrs, more especially to cultivators of that `type employed for working marshy or swampy lands, and has for its purpose to providepa means whereby such lands may be satisfactorily cultivated and without the usual unevenness and disagreeable features attending the tilling of such lands bythe present used implements.

The invention has for its further purpose to provide an apparatus which will satisfactorily work or plow large tracts of land in n one and the same operation; wherein the individual cultivators orV plows are prevent- Yed from working irregular or becoming fully hereinafter disclosed clogged ;l and wherein said cultivators or plows may be regulatedV for working at uniform depths. y

The invention has for its further purpose to providey an apparatus which will be of simple design and durable construction, which may be readily manipulated without and which will be comparatively inexpensiveto manufacture.

With these and other objects in view, the invention consists in the noveldetails of construction and arrangement of parts more and particularly pointed out in the claims.

Referring to the accompanying drawings forming a part of this specilication in which like numerals designate like parts in all the views Figure 1 is a perspective view of the apparatus complete;` Fig. 2 is a longitudinal sectional view taken on the line 2*2 of Fig. 1'; Fig. 3 is a top plan view of the cultivator attaching frame which is carried by the stage; and, Fig. 4 is-a transverse sectional view of the complete apparatustaken on the line 4-4 of Fig. 1.

s Referring to the construction in detail, the same consists of a platform or stage, and which will hereinafter be referred to as a stage, rality of of ribs 3, of substantially inverted U-shaped design in cross section. The structure is further reinforced through the medium of a plurality of clamping plates 4 which over-lie said ribs 3 adjacent the rear end of the structure, and are secured to the trough sections 1 by rivets 5, or in any other approved manner. The several sections l and ribs 3 are connected and further reinforced through the medium of a beam 6 disposed diagonally and transversely of the stage, and a similar versely and at the fore part `of the structure. That portion 8 of the stage in advance of, the beam 7 is disposed beam 7 disposed transslightlyV upwardly to the end that said stage may be dragged across the field to be cultivated more easily, and to avoid obstacles, as will be appreciated. The means for dragging the stage may consist ofany qechanical or animal power connected to the draft appliance consisting of the chain 9 and draft bar 10. The stage, as shown by way of illustration in the accompanying drawing, may be constructed of metal throughout and in which instance the several elements above referred to will be of any appropriate sheet metal, but the stage may be constructed equally as well of wood and will give the same service.

frame of substantially that design shown inY Fig. 3, consists of a plurality of bars 11, 12 and 13 of relatively different lengths, and connected by a cross bar 14 at the fore end, and by cross members 15 at the rear end thereof. The frame is detachably connected to the stage at its forward end through the medium of a coupling bar 16, that passes through the registering openings of lugs 18 and 17 carried by said frame and beam 7 of the stage, respectively. At the rear end, said frame is connected to the stage by a 'bar 19 which passes through an aperture formed in one of the cross members 15 of the frame, as clearly illustrated in Figs. l and 2. Said cross members 15 are provided each with a pair of apertured lugs 16a designed to receive a rod 17El to Y vwhich the cultivator, or plow,

nected to the several Y to" 'Y so Y pawl. 30 carried byY adapted to be actuated .by .the usual de-` -30 Ywith Ithe foregoing,

Vconstruction of apparatus p is hingedly connected. The' cultivatorwhich, in the instance shown, comprises gang plows, isV conmembers` 15' of the frame through the medium of theA hinged rods 17a, and disposed in stepped or diagonal relation transversely of the stage, and the shares20 offsaidplows'are located to work within the'recesses X at theV rear of the stage to provide whichthe rear end 2l of each 'trough 1 is cut away diagonally.V ln

addition tothe plows, the cultivator shown herein','is`provided.with colters 22 rigidly i supported on Vthe plow beams 28 and workbetween the stageY sections in spaces 24 provided therebetween. .Y

An elevating means is provided for regulating or setting the plow shares to work the earth atvariable depths, and said means consists of a lever 25 secured to the plow beams by'the'bar 26 and carrying, by arms 27, a fulcrum roller which rests, and is shiftable, on Vone of the stage sections to vary the crum point. The position of elevation of the Yplow shares, together with the colters 22, is secured throughthe medium ofa ratchet bar 29 mounted on the plow beams, and a the lever 25 which is vice 31.'` An apparatus constructedV in'.- accordance and when used for culsoggy ground, operates press or compact the vearth due tol the weight of the stage and cultivatorssupported thereby, and the earth thus pressed is firm and presents a fiat surface, which vcan then Vbe more effectively worked by' the colters and plows which trail behind the stage yin the process of cultivation, This Vthus avoids the disadvantages attending thev use of wheel cultivators in marshy lands where ythe ground is not sufficiently stable Vto, support the wheels that carry the frames of the cultivating implements, that the wheels, and sometimes the frames also, are buried in the wet, loose earth and tivating. marshy or absolutely preventthe plow from operating f at all. Y

It is-obvious that those skilled in the art may'varythe details of construction and arrangement ofrparts, without departing from thel spirit of my invention, and therefore, I do not wish to be limited to the above disclosures, eXcept as may be required by the claims.

vW'hat I claim is 1..The combination with a cultivator of an earth compressing stage associated therewith and adapted to be dragged across and in contact withthe ground withpthe cultivator inthe cultivating operation, substan` tially as described.. Y

2. The combination with a cultivator of constructed with a lstage adaptedV to bev I ground in advance of A ing operation; andS adjustable. meansV for holding said plow ing elevations, substantially as described. with the consequence i al stage constructed at its vide stepped recesses arranged transversely fr ame deta'chably hinged connections an earth compressingstage connected-to theV an earth compressing stage supportingV the cultivator and adapted to beV dragged across and in Contact lwith the ground in advance of theV cultivator; and means for elevating the'cultivator to regulate the earth working depth thereof, substantially as described,VV
